  • the IF-THEN type proposition stored in the step 14C is read from the intermediate data memory unit 5g (step 15A).
  • the IF-THEN type proposition is then supplied to the image data memory 3 through the image data output unit 5d and stored into the image data memory 3 (step 15B).
  • the IF-THEN type proposition shown in FIG. 30 is displayed on the display device 1 by the image display controller 2.
  • the IF-THEN type proposition read in the step 15A is supplied to and stored into the design reference memory 7 through the design reference output unit 5h.
  • the IF-THEN type proposition (design reference) stored in the design reference memory 7 is used for layout design of a plant by a CAD apparatus.
  • a CAD apparatus For example, by docking the design reference making apparatus of the present embodiment with a design support apparatus shown in Japanese Patent Application No. 60-53764 (U.S patent Ser. No. 838,957) (or by adding a program shown in FIG. 7 of the Japanese Patent Application No. 60-53764 to the computer program stored in the process memory unit 5h of the processor 5 of the present embodiment), the plant layout and the making of the design reference can be accomplished by one apparatus.
  • any design drawing can be displayed on the display apparatus 1 and the design object which is the object of the design reference can be designated while the operator watches the image. Since the restrictive item of the design reference can be readily selected, high precision (error-free) design reference can be made and the operation time can be significantly reduced. Since the specification data of the design object can be displayed on the display apparatus 1, necessary items can be correctly selected and high precision design references can be made.
